SAVER_NONRESPONSIVEPROCESS

SAVER_NONRESPONSIVEPROCESS: recorded condition

SAVER_NONRESPONSIVEPROCESS has value 0x00000194 and identifies nonresponsive process detection. For SAVER_NONRESPONSIVEPROCESS, the SAVER family is used as a diagnostic classification; public parameter semantics are not available for this value, so the producer, dump type, and accompanying event payload define how it must be read.

Evidence that matters for SAVER_NONRESPONSIVEPROCESS

Preserve process id, UI and worker stacks, wait chain, CPU samples, locks, pending I/O, COM/RPC calls, and message-queue state. Differentiate deadlock, blocked I/O, message-pump starvation, sustained CPU work, and dependency timeout.

For SAVER_NONRESPONSIVEPROCESS, record the exact Windows build, process or package identity, module versions, capture timestamp, and component that requested the report.
For SAVER_NONRESPONSIVEPROCESS, determine whether the artifact is a live kernel dump, application dump, WER report, test-harness result, or a true system bug check before choosing debugger commands.
For SAVER_NONRESPONSIVEPROCESS, follow the stack and provider-specific fields back to the operation that stopped progressing; the symbolic bucket is a routing clue rather than a root-cause verdict.

What distinguishes SAVER_NONRESPONSIVEPROCESS

A restart restores availability but should follow collection of a process dump and the wait evidence. For SAVER_NONRESPONSIVEPROCESS, compare neighboring SAVER values only after the evidence above identifies the same producer and lifecycle stage; similar-looking names can describe different capture triggers.

Recovery after evidence collection for SAVER_NONRESPONSIVEPROCESS

Preserve the original dump and logs before restarting the affected process or machine. For SAVER_NONRESPONSIVEPROCESS, A restart may restore service, but durable recovery requires correcting the component, dependency, resource limit, firmware, or application state demonstrated by the captured evidence.
